CLEVELAND — A doctor was convicted of health care fraud and other charges for prescribing painkillers that prosecutors say resulted in the deaths of two patients under his care.

Dr. Jorge Martinez contends his clinics in Parma and Boardman in northeast Ohio offered people relief from chronic pain.

Prosecutors say he often prescribed medication such as OxyContin, Zoloft and Valium to people already hooked on drugs. But he rarely gave a prescription until after the patient agreed to receive injections to treat pain.

Martinez then billed Medicare, Medicaid, the Ohio Bureau of Workers’ Compensation and private health insurance plans for the injections.
